C++ date & time with milliseconds

Question

Requirement

I need to retrieve the date and time including milliseconds in C++11 on Windows. If possible, beginning earlier than 1970.

I also need to be able to extract year, month, day, hour, second and millisecond from the date/time variable.

What I've tried

• time() only returns seconds.
• clock() doesn't return a date, only time since last system start. Good for measuring elapsed time, tho.

Note: It only has to work with Windows. Linux is not required.

Solution

If you are using c++11, you should use chrono which allow you to manage time easier. It gives you a few methods to "cast" your time in whatever units you want (seconds to milliseconds, ...) and can manage ctime variables too.
